This is a lesson I found on Thinkfinity. As usual it has given me an idea for a much bigger, better project that will include kids in groups and having them go through a series of excercises, mostly geography but some ocean current information included, where they will attempt to locate a fictional shipwreck. This lesson would be use as a precursor to that unit. (Also as per usual it will probably create a whole lot more work added to my already full load.)
